It seems like you just have an excessive bit of a phobia that happens to revolve around encounters with men. You are no different then alot of guys here - the typical humble SA dudes appreciat and respect the female so completely, that we don;t know where to even start when we interact with thm. Sounds like you.
DAting with SA can be a big sloppy mess. I get sooo shy when a girl smiles and flirts with me, which is often. I usually avoid at all costs cause I imagine I'll blow it or they are just being nice to be nice. I have never ever been condifent enough to initiate conversation, and if it got past that, the romance unless i was completely and utterely sure she'd be game. Usually,the type of reassurances I need are apparently dangerously close to slut-levels, which believe me explains why I'm usually single for long stretches and date for no more than a week or two. This is why I am just not having sex for awhile and just being "friends" with all the girls I meet. Not thinking with my smaller head has helped me form relationships with women that are friendly and flirty and I feel in control of in that I won't be sad if rejected!
Take away the tension, and the opposite sex can't resist you.
And reading your post, you seem pretty smart. I don't care what you look like, if you are smart, have clean teeth and smell good too, you're like a magnet and dudes'll be paperclips.
Good luck. Besides, dudes always act like they think they need too and you are not an object of judgement but when you talk to us you become a modification factor - namely we mold our behaviour toward based on what we think we'll get us a positive reaction from you, some go queit, some go "Asshole" mode - so go for the quiet ones and ask us questions: No need to fear us monkeys.
